Michael has a new habit of putting things back where they came from.  Even when it's unnecessary (e.g. he won't accept toys from strangers--he always hands it back), there's still no harm done, right?  At least, not until I give Michael a snap pea sample from the supermarket; he licks it, doesn't like it, and leans over and puts it back in the bin before I realize what he's up to.  Oy.
